Here is curl test output.

curl -X GET "localhost:9200/_cat/nodes?v&pretty"
ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name

Any help will be appreciated.

Question 2

Hi, how did you fix this? I get the same error while building on the server.

Question 3

After building up your container update host url for elasticsearch. Type following command from CLI

bin/magento config:set catalog/search/elasticsearch7_server_hostname elasticsearch

By default, elasticsearch host url is localhost

Question 4

ooo man struggling on this for like more than an hour although tried changing this same value in the database manually but don't know why it didn't worked now its working

Question 5

In your .env file the elasticsearch host is http://elasticsearch:9200 while in your install-command elasticsearch host is set to localhost. Change the elasticsearch host in your Magento Configuration (Backend) to http://elasticsearch.

Question 6

In my case Elasticsearch wa installed via brew (Mac) on Host.

And for access from Docker used Elasticsearch host - like host.docker.internal http://host.docker.internal

just try in Docker cli

curl -X GET "http://host.docker.internal:9200/_cat/nodes?v&pretty"

Question 7

Make sure 'catalog/search/elasticsearch7_server_hostname' is set with proper hostname in core_config_data of db table.

For local magento I have set the value to 'localhost'. Please check screenshot for more clarification - https://i.sstatic.net/lynIX.png
